reconciliation difference must be zero before reconciling error

Hi exports

Iam using 9.3 HANA PL12.

when i create the AP Invoice from the Landed cost, i am getting this error "reconciliation difference must be zero before reconciling".

>>normally when i use the same base amount in the particular line(1st line as in pic) , then it is working.

>>But actually when i increase the amount then try to add it, then it is showing this error.(pic attached)reconcilation-error.png

>> For information, before upgrading to PL12. In this PL5 , it was working.

thanks with Regards
